ABSTRACT:
A hand-held showerhead structure includes a handle portion, a water-outlet base, and a rotary member. The rotary member includes an outlet valve and is mounted on the water-outlet base in a rotationally adjustable manner, which is turned by a user to adjust to a desired water-spraying mode. A plurality of annular chambers is defined between a middle cover and a lower cover of the outlet valve. A plurality of arc-shaped flow-guide ribs distributed radially and separated from one another is protruded from a top wall of the lower cover opposing to an annular chamber in an outer peripheral area. A plurality of open-ended arc-shaped flow-guide channels is accordingly defined between the flow-guide ribs. Moreover, a plurality of outlet holes is arranged in flow-guiding directions of the flow-guide channels. Therefore, the showerhead positioned in such a water-spraying mode is capable of achieving a uniform water-spraying effect at a larger spraying area.
